Separating the Components of a Ternary Mixture
T.A Katherine Turner
Introduction The purpose of the experiment is to separate components of mixture of sand (SiO2), salt (NaCl), and chalk (CaCO3).
The first reaction shows the separation of calcium carbonate from the mixture.
In the second reaction we use the product of the first reaction (CaCl2) and change it back to calcium carbonate (CaCO3) by mixing CaCl2 with potassium chloride (2KCl).
To separate the components of mixture of sand, sodium chloride and calcium carbonate.
Materials and Equipment
1. Two beakers
2. Experimental mixtures
3. Distilled water
5. Filter paper
6. Evaporating dish
7. Buchner funnel
8. Weighing machine
9. Conical flask
10. Hydrochloric acid(HCl)
11. Potassium carbonate(K2CO3)
12. Rubber hose pipe
1. Obtain two clean beakers, then weigh and label them.
2. Get the mixture and weight it. Then add 50ml of water to beaker 1 and stirrer the mixture.
3. Prepare the funnel with a filter paper with conical flask under it. Then filter as much as possible. Then take the conical flask and put it above a beaker with boiling water and wait for the water to evaporate.
4. Measure sodium chloride. Then take the residue from the filter paper and wash out by distilled water and pour into an evaporating dish.
5. Heat it to evaporate the water. Then add 8ml of 3M Hydrochloric acid (HCl) to the mixture. Then take the residue and heat it to get the sand.
6. Measure the sand. Then heat rest of the mixture and talk the chalk and weight it.

Discussion / Conclusion The purpose of this experiment is to separate the component of mixture which is done successfully with a minor percentage Error (5.2). The weight of
